To all wil/0111, it nul/y conce/"lt: Be it known that l, JOHN H. BELL, a citizen of the United States, residing at lladdoneld, in the county of Camden and State of New Jersey, have invented certain newV contact and the consequent curling up and wear of its edges, which is usual where belts are guided by flanges at the edges of the drums; second, to form the driving-drums and carriers of skeleton construction with.

open spaces or interstices, so that if any part of the conveyed material overruns or falls from the belt its lodging between the belt or carriers and drums will be cilfectually prevented or reduced to a minimum, as such lodgment creates undue friction and wear of the parts and tends to distort the belt; third, to form the driving-drum and the inner side or face of the belt to interlock and whereby the beltk shall be positively driven by the drumindependent of frictional contact. By using drums with bars and intervening spaces and by also having bars secured to the belt there is great pulling power. The car'- rier-d-ruln may be of the same diameter as the driving-drum or of other diameter, as desired. In narrow carriers a single narrowfaced pulley may be used at each side of the central guiding-space. i

THe invention is illustrated in the accompartying drawings, in which similar parts are esignated by similarl reference characters in all the views, and in which- Figure 1 is a side elevation. Fig. 2 is a plan or top view. Fig. 3 is an inside view of a portion of the belt. 4 is a face eleva, tion of a part of the driving-drum and a section of the other part o'n line :n Fig. 1.

A suitable framework 1 supports shafts 2 3, and there will 4be drivin means-such as a gear, a sprocket wheel an chain attached to shaft 2 for driving pur oses, or any suitable driving means-provi ed by thefmachine to which the conveyer is attached, which is not shown, being no part of the invention. Upon shaft 2 are mounted pulleys 4 5 6 7 and upon carrier-shaft 3 there are mounted pulleys'8 9 10 v11. Pulleys 4 7 are fixed to have their outer edges as'far apart a's the width of the belt 12 and pulleys 8 11 may be the same or less apart, while pulleyss 6 and 9 10 are near the middle of their respective shafts, but with spaces 13 14 between their adjacent edges.k Secured to the peripheral surfaces of pulleys 4 5 are connecting-bars 15, spaced apart to leave spaces or openings 16.` The pulleys 4 5 when connected lby the barsv 16 form a driving-drum with an intersticed annular surface. Pulleys 6 7 are likewise conniay be provided with bars and spaces or without, as shown. Thus there are a pair of operi-faced drums for shaft 2 with 'a space 13 between them and two pairs of plain pulleys with a space 1 4 between the inner pulleys on shaft 3.

Attached to the innerface or surface of belt 12 are bars 17, which reach the entire dis- -tance across the'belt, also shorter barsI 18,

the belt, and bases 19 still shorter than bars 18. Bars 17 18 and bases 19 are'preferably secured to belt 12 by countersunk rivets 20, the bars and bases being of less thickness than bars 15 of the drums. The bars and bases are spaced apart on belt 12 so as to abut and be carried along by bars 1 5. By making bars 1,8 and bases 19 shorter than bars 17 the entire width. Thebars and bases may be shown, and one or more kinds only may be attached tothe belt to suit the material of which the belt is composed or the work the belt has to do. vSecured to the center of .bars

lugs 21, but of a orrn and size` to freely pass through spaces 13 14 to centrally guide belt 12.

I claimshafts, and pulleys connected by bars 1n manner to form drums with intersticed annular surfaces, on the shafts. v

2. In aA conveyer, a suitable framework, shafts supported thereon, groups of pulleys on the shaft, and bars secured to the/peripheries of adj acentv pulleys to form drums with Aintersticed faces. A i

3. In a conveyer, a framework, shafts supported thereon, groups of pulleys thereon, the pulleys of each group forming a drum, by means of peripheral connections, with inter*- vening spaces, and adapted to carry-a belt.

1. In a conveyer, a' framework supporting nected with bars 15.- Pulleys 8 9 and 10 11 which reach only a portion of the way across v belt is more flexible than if all areI carried its l differently arranged on the belt than as 17 18 and bases 19 are the tapered guidingreferably of circular cross-section,

4. ln a conveyer, a framework, shafts supported thereon,groups of pulleyson the shafts, the pulleys of each group forming a drum, by means of peripheral connections, withintervening spaces, and adapted to carry a belt, v and a belt e guiding space between adjacent drums. k ,j

5. In a conveyer, a'framework having means for supporting shafts, shafts therefor,

drums upon the shafts comprising pulleys, or their equivalents, each adjacent pair of pulleys at each end of the. shaft being connected at their peripheries in manner to form a drum with an linters'ticed peripheral surface, and the adjacent drums being se arated to afford a space for the passage of be t-guide's.

6.4 In a conveyer', a belt having fixed upon i' its inner surfacev a series of crosswise bars of interior surface a series of bars some o reach across the belt, andothers'which-reach only a portion of the way across, lu s-upon y the bars, and additional lugs secure to the' 'l different lengths.

7. In a conveyer, a b lt havingl fixed upon the whole breadth of its inner surface a series of crosswise bars, spaced apart, and tapered g 'g-lugs projecting vfrom the center of said bars.

8. In a conveyer, a belt having `fixed upon its inner surface a series of crosswise bars, of dierent lengths, spaced apart, and guidinglugs proj ectingfrom said bars. I

10.A In a conveyer, a beltl having upon its which means for supportingshafts, s afts therefor, l

multiple drums upon the sha ts which are formed of pulleys or equivalent means, placed apart on the shaft and connected by bars secured to their peripheries, with intermediate spaces, and projecting above the pulleys, and a guiding-space between the adjacent drums placed upon a common shaft.

13. In av conveyer, driving-pulleys and` carrier-pulleys, each having a shaft, a frame carrying the shaft-s, the plilleys placed upon their proper shafts to provide an intervening space between the pulleys on the sameshaft, and a carrier-belt having upon its inner surface projections adapted to passthrough the ntlervem'ng spaces, as means for guiding the e t. f j In testimony lwhereof I have signed my name to this specification in the'presence of two subscribing witnesses.v JOHN H.
